Odontoglossum
The Odontoglossum orchid genus originates in the neotropics, mostly the Andes mountain range. The higher-altitude species have more flowers, the lower-altitude species have fewer, larger flowers. They have a pair of calluses on the lip, near the column. The flowers of most species are very beautiful. The flower stems emerge from the base of the pseudobulb. Most plants are epiphytes.
